This causes problems with InnoDB that can't lock the ibdata1 file and will refuse to load. If I use XAMPP to only launch Apache and launch MySQL manually with /Applications/XAMPP/xamppfiles/sbin/mysqld I have no problems

Is this standard behavior?Is this something that can be changed in the my.cnf file? (I do't see where)There seem to be newer versions for Windoze (:-( will there be corresponding Mac versions that might fix this?
